Improvement in mop-heads

We, OLIVER S; GAnRErsoN andJ'oEL GAR- nETsoN, ofthe `city of Buffalo, inthe county of Erie and State of NewYork, have invented certainImhprovementsin. Mop-Heads,`of which the following is I: specification.I i i Onr improvements relate to that class of mop-heads n ,which the.movable; jaw or binder, the ends of `which are attachedto aninterveningnut, is operated l a tubular'screw iitted on and immovably-secured tothe end ofthe handle solas toy rotate with the latter, l f-andcausethesaid nut to traverse up and down thereon. v i y y" Inthis kind ofmop-head theg'cnd 'off the handle is i commonly united to the'`stationary jaw or cross-head l by means of a loose rivetor pivot pin. l

'able hinder, causesconsiderable friction and wear be- `t Lthe head ofthisrivetand the cross -head, vhich loosens, and not unfrcqucntlydestroys the con- Vne` on'j'of the latter with the handle. i i

C is thc stationary jaw lor cross-head. 1),'the movable jaw or binder;,and

E, the nut or. yoke which, connects the two ends Y thereof. This nnt maybe cast entire, or` in halves,

which are afterward united by rivets, that also secure l the-ends of thebinder in place, as shown.

The cross-head is cast with a longitudinal secured in the socket c ofthe cross-head by a rivet, t', Its connection with the tubular screw ismaintained p by aninwardly-projecting flange, b', at the end of the yThe rotation of the handle, in adjusting the movscrew, which engageswith the outwardly-projecting Ailange h. of the bearing, as clearlyshown in Fig. III, whereby the separation otlthepart's is prevented,

, while'the screw isV left free-to' turn around the flanged vhead ofthev bearing-during` the adjustment of the movable jaw.

on is the indented surface of the cross-head snr-` `rounding the socketc','and u yu are a number, of teeth Y or projections at the end. of 'thetubular screw, de-

signed to tin and engage withthese indentations.

In putting up our improved mop-head, the bearingblock H is iii-stinserted in the tubular-screw, and then' riveted to the cross-head. Thehandle is now fasti cned in the screw, and the nut arranged on thescrew7 andthe ends ofthe hinder secured thereon. f

The mop-cloth being clamped between the crossvhead and bindcr,`byrevolving the handle `and tubular screw within` the nut E in the usualmanner. The serrated connection between the end ofthe screw andcross-head prevents the handle from unscrewing and releasing the clothduring the ordinary use of the mop.

When the cloth is requiredto'be released or adjusted, the application ofa greater or lesser force, according to the tightness with which thecloth was clamped,

will overcome this fastening, andcause the teeth utc slide overtheindentedsurfacc aa as the handle is revolved, the binder, whichoperates as a spring, yielding suticiently to permit of this partialseparation and movement.

yturn around in-,actuating the binder. In suoli case,

as the `parts are not riveted together, the cross-head will separate'from the screw as the binder is released.

lo prevent the handle from being entirely withr Barrato, Naw Y groove, v

dmwnffrom the nut, wev make the thread of theI screw to lterminatebefore it reaches the end of tlie screw,

so as to leave :n bead or stop, s, to arresti-he movement, as clearly.shown. Y
